Stamen number relative to petals: haplostemonous = 0; diplostemonous = 1; anisomerous (less than petals) = 2; numerous = 3.
Each flower is characterized by an actinomorphic, pentamerous perianth composed of a whorl of sepals and a whorl of petals, a haplostemonous androecium with antesepalous stamens, and a bicarpellate gynoecium; the styles of the flowers are fused to free, and the single stigma is capitate.
In most Cyperoideae, however, only one haplostemonous whorl of stamens remains.
